on management.php, what variable are you using for the dynamic plugins?
You would use that same variable in the menu to dynamicly set the class=current on the correct menu item.
for example, if i set the dynamic plugins to use a query string variable named "action":
management.php?action=results - loads results.php
management.php?action=search - loads search.php
management.php?action=update - loads update.php
etc...
you would add an if statement to the menu code to dynamically set the class:
<li><a href="management.php? action=results"<?php if(isset($_GET['action']) && $_GET['action'] == "results") echo(" class=current"); ?>>results</a></li>
<li><a href="management.php? action=search"<?php if(isset($_GET['action']) && $_GET['action'] == "search") echo(" class=current"); ?>>search</a></li>
<li><a href="management.php? action=update"<?php if(isset($_GET['action']) && $_GET['action'] == "update") echo(" class=current"); ?>>update</a></li>
